A
Enzymes are consumed during metabolic reactions.
B
Enzymes store genetic information for metabolic pathways.

D
Enzymes provide energy for metabolic processes.
Verified step by step guidance
1
Begin by understanding the role of enzymes in biological systems. Enzymes are proteins that act as catalysts, meaning they speed up chemical reactions without being consumed in the process.
Recognize that enzymes lower the activation energy required for a reaction to occur, allowing metabolic processes to proceed more efficiently and rapidly.
Consider the statement 'Enzymes are consumed during metabolic reactions.' This is incorrect because enzymes are not consumed; they remain unchanged after facilitating a reaction.
Evaluate the statement 'Enzymes store genetic information for metabolic pathways.' This is incorrect because genetic information is stored in DNA, not enzymes.
Understand that the correct statement is 'Enzymes act as catalysts to speed up metabolic reactions.' This accurately describes the primary role of enzymes in metabolism.
